Centre of Rotation
******************

Methods from :mod:`httomolibgpu.recon.rotation` module are used for automatic determination of the centre of rotation (COR). The centre of rotation (COR) is a critical parameter in tomographic reconstruction. An incorrect COR introduces characteristic reconstruction artefacts, including blurring, double edges, and duplicated structures. See more about CoR `here <https://diamondlightsource.github.io/httomo/howto/httomo_features/centering.html>`_
